Miniature rose plant named ‘Poulpar071’

ABSTRACT

A new miniature rose plant that has abundant, orange and pink blend flowers and attractive foliage. The variety successfully propagates from softwood cuttings and is suitable for year-round production in commercial glasshouses. This new and distinct variety has shown to be uniform and stable in the resulting generations from asexual propagation.

Botanical designation: Rosa hybrid.

Variety denomination: ‘Poulpar071’.

SUMMARY OF THE INVENTION

The present invention constitutes a new and distinct variety ofminiature rose plant which originated from a controlled crossing betweenthe female seed parent, an unnamed seedling, and the male pollen parent,also an unnamed seedling.

The two parents were crossed during the summer of 2006 and the resultingseeds were planted in a controlled environment in Fredensborg, Denmark.The new variety, named ‘Poulpar071’, originated as a single seedlingfrom the stated cross.

The new variety may be distinguished from its male pollen parent andfemale seed parent primarily by flower coloration and growth habit.

The objective of the hybridization of this rose variety was to create anew and distinct variety for use in the floral industry with uniquequalities, such as:

-   -   1. Uniform and abundant pink and orange blend flowers;    -   2. Vigorous, but compact growth when propagated on its own        roots;    -   3. Durable flowers and foliage which make a variety suitable for        distribution in the floral industry; and    -   4. Year-round flowering under glasshouse conditions.

This combination of qualities is not present in previously availablecommercial cultivars of this type, known to the inventor, anddistinguish ‘Poulpar071’ from all other varieties of which we are aware.

As part of the rose development program, Mogens N. Olesen germinated theseeds from the aforementioned hybridization during winter of 2006 andconducted evaluations on the resulting seedlings in a controlledenvironment in Fredensborg, Denmark. ‘Poulpar071’ was selected in thespring of 2007 by the inventor as a single plant from the progeny of theaforementioned hybridization.

Asexual reproduction of ‘Poulpar071’ by traditional budding and rootedcuttings was first done by Mogens N. Olesen in the nursery inFredensborg, Denmark in July, 2007. This initial and other subsequentasexual propagations conducted in controlled environments havedemonstrated that the characteristics of ‘Poulpar071’ are true to typeand are transmitted from one generation to the next.

DESCRIPTION OF THE DRAWING

The accompanying color illustration shows as true as is reasonablypossible to obtain in color photographs of this type, the typicalcharacteristics of the buds, flowers, leaves, and stems, of‘Poulpar071’.

Specifically illustrated in the drawing are flowers at various stages ofdevelopment, flower in parts, leaves, and stems.

DETAILED DESCRIPTION OF THE VARIETY

The following is a description of ‘Poulpar071’, as observed in itsgrowth in a glasshouse in Half Moon Bay, Calif. Observed plants are 3months of age, and were grown on their own roots in 4 inch pots. Colorreferences are made using The Royal Horticultural Society (London,England) Colour Chart, 2001, except where common terms of color areused.

For a comparison, several physical characteristics of the rose variety‘Poulpar041’, U.S. Plant Pat. No. 17,889 are compared to ‘Poulpar071’ inChart 1.
